Development of Ultra-Wideband 500 MHz – 20GHz Human Skin Phantoms for Various Microwaves Based Biomedical Applications

In this paper we proposes an artificial tissue mimicking(TM) phantom for skin layer which mimics the physical and dielectric properties of human skin layer. We have fabricated a low coast, malleable and long lasting skin layer phantom.We have chosen semi solid type phantom for the skin layer. The size and thickness of the skin layer is chosen based on the average thickness of human tissue. Altering the ingredient composition wisely we can alter its dielectric properties also. The performance of the fabricated set of phantoms is carried out using an open-ended coaxial slim probe system by Agilent Technologies. We have developed some different sets of skin layers to analyze how its properties are varied depending on the ingredient composition. The different set of skin layers are tested at a frequency range of 500MHz-20GHz.
